Vibrio vulnificus kills Florida resident, prompting coastal health alerts

An 80‑year‑old resident of Palm Beach County, Florida, died after contracting a Vibrio vulnificus infection, the first death linked to the bacterium in the United States this year. Florida health officials reported 12 infections to date and noted the state has the nation’s highest rate of Vibrio cases. The bacterium, which thrives in warm, brackish coastal waters, can cause necrotizing fasciitis when it enters the body through open wounds or by consumption of raw or undercooked shellfish such as oysters.

In Louisiana, five residents have also died and four more have been hospitalized with Vibrio vulnificus infections, all of whom had underlying health conditions. State health officials emphasized that the infection is most common from May to October and advised at‑risk individuals to avoid raw oysters, keep wounds covered when in seawater, and seek prompt medical care.

Infectious‑disease specialist Matteo Bassetti warned that rising summer temperatures are expanding the geographic range of Vibrio bacteria, prompting the European Centre for Disease Prevention and Control to issue monitoring tools for coastal waters. The U.S. Centers for Disease Control and Prevention recommends protective measures for people with open wounds or weakened immune systems.
